What hard drives are compatible with laptops?

I use a laptop with an HDD on its death spin. I wanted to buy a 500GB HDD to replace my current 320GB. However I was told not to do so and rather buy the same model that came with the laptop.

Can you please tell me the criteria for compatibility apart from SATA/eSata interface?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

As you can read in our FAQ, shopping recommendations are off topic. Your question is also a little localized to your current model – we can't have one question on which HDD is compatible with every laptop there might exist. Fact is: All typical laptops use 2.5" SATA disks these days. You can buy almost any. – slhck Sep 20 '12 at 11:12

you don't have to buy the same model of HDD as you have, you can use any compatible (2,5" SATA) HDD. so look for a 2,5" SATA 3.0Gb/s 500GB disk

Do all laptops use 2.5" drives? – Fasih Khatib Sep 20 '12 at 11:08
No, but 99% of them do. It if you had one which did not then you would probably be aware of that (or for nothing else as due to the hefty price tag and a lot of marketing stating 'ULTRA MEGA SUPER MEGA small maximum weight reduction' etc etc. :) – Hennes Sep 20 '12 at 11:09
I don't know of any current laptop model that has 3,5" disk, so I would have to say yes, And you provided your current model of disk which is 2,5" SATA 3.0GB/s… – rAlen Sep 20 '12 at 11:11
@FasihKhatib - We don't do product suggestions on Stack Exchange websites. I have provided you two HDDs that are EXACTLY the same HDD just larger. I likely shouldn't even have done that to promote the concept of good valid questions on this website. – Ramhound Sep 20 '12 at 11:17
@FasihKhatib - I went ahead an answered it because your question other then being not on topic for this website was well written. As I pointed out the two HDDs I suggested are exactly the same except for their size. – Ramhound Sep 20 '12 at 11:36

Can you please tell me which other HDDs are compatible with my laptop or the criteria for compatibility apart from SATA/eSata interface?

Any SATA 2.5" HDD will be compatibile with your laptop.

Seagate Momentus 7200 750 GB 7200RPM SATA 3Gb/s 16 MB Cache 2.5 Inch Internal Notebook Hard Drive -Bare Drive ST9750420AS

Seagate Momentus 7200 500 GB SATA 3Gb/s NCQ 16MB Cache 2.5 Inch Internal Notebook Hard Drive ST9500423AS - Bare Drive

Both of these HDDs are the same model as your previous HDD just larger.

500GB for $77 and 750GB for $79. Black magic sorcery? :p – Fasih Khatib Sep 20 '12 at 11:13
@FasihKhatib - Both of those models are several generations old. – Ramhound Sep 20 '12 at 11:16
